    Hi all! I am new here, and rather than starting a new thread, I was wondering if you could give me some advice here. We have a Prius 2018 (Two Eco) and we just bought a charger (Noco genius 2). But before using it, we had to figure out what type of battery we have, because the charger requires that we specify if we will be charging a regular or an agm battery. We called the dealership and they said that the 12v battery in our car (which has never been replaced since we bought it) is AGM. But, I keep seeing discussions (in this and other forums) referring to gen 4 prius battery as a regular wet lead-acid battery. I am attaching a photo of the battery and I was wondering if anyone could help me figure out what type of battery this is. Is this how an agm battery would look like?

    It's not an AGM. The charger will likely do a rudimentary assessment of the battery before commencing the charge program. If it refuses to start, it's a fairly safe bet you should replace. Electronic load testers could confirm; battery retailers typically have such testers and will usually test for free.

    There's some info here about compatible batteries.

    @Elektroingenieur is on top of it. He may have even linked in this thread, but between my limited brain cells and dated phone, all I can do is invoke his "bat signal".

    The battery in your photo looks just like the one in my car, which is definitely a “maintenance free” flooded (wet) type, not an AGM battery, as @Mendel Leisk kindly mentioned. The dealer may have been confused because 2015 and older Prius cars, and Prius c and Prius v models, do use AGM batteries.
    See my September 20 posting.
    For bats, I recommend the Congress Avenue bridge.

    AGMs wouldn't have the filler caps.
